Small tangential flow ultrafiltration system

TFF Overview
Understanding tangential flow ultrafiltration systems

Brief Introduction of Tangential flow filter (TFF)
Tangential flow filter (TFF), also known as cross flow filter (CFF), refers to the liquid flow direction and filter direction perpendicular to the filter form. Liquid flow creates a shear force on the surface of the filter media, reducing the stacking of the cake layer or gel layer, thus ensuring a stable filtration rate.

According to the trapped particles or molecular size can be divided into microfiltration MF, ultrafiltration UF, nanofiltration NF and reverse osmosis RO. TFF technology is currently widely used in pharmaceutical, biological, chemical, food and beverage and environmental protection industries.

Brief introduction of small tangential flow ultrafiltration system
System Overview:
The small tangential flow ultrafiltration system is a set of TFF devices developed by Beijing Halls for laboratory users. It is mainly applied to TFF research of small scale or pilot scale in laboratory. The system uses imported original box-type flat film package, can achieve microfiltration, ultrafiltration, to meet the needs of laboratory diversification.

System applications:
● Cell collection, cell fluid clarification and filtration, recovery of antibodies or recombinant proteins
• Concentration and desalination of proteins, peptides or nucleic acids (DNA / RNA / oligonucleotides)
● Remove heat source or impurity molecules in the water, buffer, medium solution, equal volume of continuous dialysis
System Features:
● Sample recovery rate is extremely high, and efficiently ensure protein activity
● Filtration speed is stable, can be continuous cycle of filtration, the film surface does not form a gel layer
● Easy to linear amplification, the maximum reduction time and cost from small scale preparation to large-scale production
● Universal stainless steel fixture, matching the major brands of imported original box-type film package, which can be installed  1 to 3 pieces at the same time
● Integrated design, easy to operate, according to different needs to choose the appropriate film fixture, peristaltic pump and film package
● Stainless steel stent + raw material tank, siphon feeding, easy  for  laboratory aseptic continuous operation
